Description
[technical field]
The invention belongs to the chemistry painting industry technical field, be specifically related to a kind of interior wall with basic emulsion coating and preparation method thereof.
[background technology]
In American-European developed country, the popularity rate of water-miscible paint is up to more than 80%.But in China, the development of water-miscible paint has also just just gone on foot the expressway, though also be in weak tendency, share increases rapidly.In the near future, water-miscible paint will occupy main flow paint market.The advantage of water-miscible paint mainly contains: 1. environment friendly oil lacquer is main with pyroxylin(e)finish, polyester lacquer, adds a large amount of organic solvents in the dilution, is stranded in indoorly for a long time, can damage HUMAN HEALTH.Therefore, oil-base paint also discovered titled with the title of " stealthy killer ", be that the poisonous carcinogenic substance of a bigger part of representative still volatilizees in long-term sustained release with free TDI (tolylene diisocyanate) in the solvent-borne type paint, and the volatilization phase can reach 10～15 years.Water-miscible paint then is as unique thinner with clear water.The water-miscible paint brushing is intact can move in after doing, and need not also will wait the several months just can move in as the oil-base paint brushing is intact.2. energy-conservation solvent-borne type paint will be used petroleum resources, and especially a large amount of solvent (benzene compound and other solvent) also will refine from oil.And water-miscible paint be except resin and part of auxiliary need be refined from oil, and solvent is a water, has practiced thrift a large amount of valuable petroleum resources.3. do not burn 4. the construction simple and convenient.
At present water-borne coatings use petroleum chemicals mostly emulsion or resin as raw material; Inconsistent with the trend of current social development low-carbon (LC), environmental protection economy; The ecological emulsion of new modified polymerization natural oil is by the preparation of natural reproducible oil, meets green fully, environmental protection; The requirement of low-carbon economy is the direction of the development of following green coating.
[summary of the invention]
The object of the present invention is to provide a kind of modified poly natural oil that adopts to use basic emulsion coating as the interior wall of emulsion, can effectively reduce the use of petroleum chemicals, in order to achieve the above object, the present invention adopts following technical scheme:
A kind of interior wall is used basic emulsion coating, counts by weight, and its composition comprises: 8～20 parts in water; 2～4 parts of solubility promoters; 0.5～1.2 part of dispersion agent; 0.1～0.25 part of wetting agent; 0～40 part of pigment; 0～65 part of filler; 8～70 parts of emulsions; 0.2～1 part of thickening material; 0.1～0.4 part of skimmer.
Above-mentioned pigment is rutile-type or anatase thpe white powder, zinc sulfide white; Said filler is permanent white, coarse whiting, kaolin, mica powder, wollastonite or magnesiumcarbonate; Above-mentioned emulsion is a modified poly natural oil emulsion.
This interior wall can also comprise 0.1～0.4 part of sanitas with basic emulsion coating, and sanitas is a RH-893.
Used solubility promoter is terepthaloyl moietie or Ucar 35; Thickening material is hydrophobically modified Vestolen PP 7052 soda acid swelling type, hydroxyethyl ether cellulose, polyurethane-type; Skimmer is the compound skimmer of aliphatic hydrocarbon, and the froth breaking active substance is polyethylene wax, metallic soap, hydrophobic inorganic silicon and organopolysiloxane.
As preferably, using the HLB of wetting agent adjustment coating system is 12～13, can adjust the wettability and the color developing of coating to greatest extent, makes the mill base with different hydrophilic or hydrophobic performance all reach good compatible effect; Dispersion agent is the polycarboxylate salt dispersant, and the mercerising finish paint can be selected the amine salt dispersion agent, and zero diopter can be selected the sodium salt dispersion agent for use
The present invention also provides the preparation method of a kind of interior wall with basic emulsion coating, may further comprise the steps:
1) solubility promoter, wetting agent, dispersion agent, skimmer are added in the entry, stirring at low speed is even, obtains dispersed slurry;
2) in dispersed slurry, add skimmer, emulsion successively;
3) adding thickening material adjustment viscosity is 90-110KU, promptly obtains basic emulsion coating.
Also be included in stirring at low speed in step 1) and evenly add pigment and filler in the back, high speed dispersion or sand milling pigment, filler, refilter less than 50 μ m up to fineness, obtain dispersed slurry; Stating step 2) in after adding skimmer, also added sanitas.
Emulsion of the present invention is a modified poly natural oil emulsion, specifically is that application number is the emulsion in the one Chinese patent application of CN 201010159350.4.Because the rotating disk of whipping device is different, can not limit with rotating speed, the present invention explains to it that with LV the high speed among the present invention is meant that LV is 20～25m/s, and lower velocity is meant that LV is 3～5m/s.
A kind of interior wall of the present invention is the interior wall basic emulsion coating product of being processed by renewable emulsion with basic emulsion coating; This basic emulsion coating product has water-fast, alkali proof advantage; Simultaneously under the ultraviolet effect, also can keep preferable performance, also have functional performances such as freeze-thawing resistant, and this basic emulsion coating is nontoxic, low VOC; Can satisfy the application requiring of present interior wall, have positive environment protection significance.
